McCartney divorce takes ugly turn Source: UPI LONDON (UPI) -- Sir Paul McCartney's high profile British divorce from his estranged wife Heather is getting ugly, The Mirror says. Heather has expressed outrage at being blamed for "unreasonable behavior" regarding the break-up, the tabloid reported. Pop singer and former Beatle McCartney has insisted that he wants "a clean break." "Paul just wants to get this over as quickly and cleanly as possible and put the whole sorry episode behind him," a friend of McCartney's told The Mirror. Up until now, the couple have stressed that their main concern is their 2-year-old daughter, Beatrice. However, a spokeswoman for Heather yesterday said her client is angry about the recent claims and intends to fight them in court.
